Lost in the background

Associate Professor Derek Arnold has weighed in on the latest controversy in cricket with an article on The Conversation website:

"People may be able to see a pink ball, but that doesn’t mean they can accurately judge its velocity."

"Speed perception is a special property of vision, tapping specialised mechanisms and brain structures."

"Human motion perception relies on brightness differences. When brightness differences are small, we can have trouble judging speed. Worse, people tend to see things as moving more slowly than they actually are when there are only slight brightness differences."
